THREAD-CUTTING TEMPLE FOR LOOMS.

Specification of Letters Patent. Patented June 22, 1920,

Application filed September 25, 1919. Serial No. 326,210.

To all whom it may concern:

Be it known that I, EDWARD S. STIMPSON, a citizen of the United States, residing at Hopedale, county of Worcester, State of Massachusetts, and whose post-oflice address is Hopedale, Massachusetts, have invented an Improvement in ThreadCutting Temples for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in thread cutting temples for looms and. the object thereof is to provide such a thread cutting temple in which means are provided for retaining the slidably mounted and. backwardly and forwardly movable cutter in the body of the temple in case of the breakage or disconnection of the usual spring which connects the cutter to the body and acts to move the cutter in one direction.

It sometimes happens that during the operation of the loom this spring becomes broken or disconnected allowing the cutter to drop out. When this happens the cutter is liable to cause great damage to the loom or to the cloth being woven.

The objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claim.

In the drawings- Figure 1 is a view in side elevation of a thread cutting temple embodying a preferred form of the present invention.

Fig. 2 is a view in cross section taken on the line 22 of Fig. 1.

The thread cutting temple shown in the drawing is of the usual and familiar type. It comprises a bar 1 by which it is attached to the loom terminating in a body 2. The body is provided with the usual pod, cap and roll, the construction of which is not material to the present invention, and all of which is fully disclosed in prior patents such as my Reissue Patent No. 14,420, granted January 8, 1918.

The temple is provided with suitable mechanism for cutting or severing the weft ends at the selvage. For this purpose there is usually provided a fixed blade 3 and a movable cutter 4;. This movable cutter is mounted to slide and move backwardly and forwardly in a guideway 5 formed longitudinally of the temple body. This cutter is usually of the shape substantially .as shown and includes a depending heel 6 adapted to be struck by the lay upon its forward movement. The cutter is held in place and given its movement in one direction, as rearwardly, by a wire spring 7 connected at its upper end to a boss 8 on the temple body and at its lower end. to a boss 9 on the heel 6.

It sometimes happens that owing to the shock and jar of the operation of the loom this spring 7 becomes broken or disconnected. This leaves the cutter free to be jarred or thrown out from the guideway 5 and when this happens it may fall into such a position as to damage the cloth or smash or injure some of the moving parts of the loom.

The present invention provides means for retaining the cutter in place in case the spring 7 becomes broken or disconnected,

while at the same time permitting the re-,

quired movement of the cutter in the guideway.

. A simple and preferred form of means for securing this result is provided by the screw 10 which connects the temple body and the cutter and is secured in one of these parts and engages a longitudinal recess in the other of these parts. As shown, the screw 10 is threaded into the side wall of the temple body 2 and projects into a longitudinal recess 11 in the cutter. It will be seen that the cutter may slide and move freely backwardly and forwardly, but that if the spring 7 is broken or disconnected this screw will prevent the cutter from being thrown or falling out of the temple body.

Such a construction may be readily adapted to existing temples and may be readily embodied in new temples at a very small expense and efliciently secures the desired results.

Having thus described my invention what I claim is new and desire to secure by Letters Patent is- A thread cutting temple for looms compris ing a body presenting a guideway, a slidably mounted cutter backwardly and forwardly movable in the guideway, a spring connecting the body and cutter and acting to move the cutter in one direction, and a screw connecting the body and cutter, said screw being secured in one of said parts and engaging a longitudinal recess in the other of said parts whereby the movement of the cutter is permitted while its separation from the body is prevented in case of the breakage or disconnection of the spring. 10

In testimony whereof I. have signed my name to this specification.
